His mother, Tiffany McPherson of Winter Haven, made a post on social media last month requesting letters to help cheer up Carter, the article stated.

But she never expected her request to go viral, when countless cards began arriving in the mail sharing positive thoughts with Carter, WKMG reported.

Carter has been in remission for over a year now, but he continues to receive chemotherapy once a month at Arnold Palmer Hospital as part of a three-year treatment plan, according to a report by Fox News.

The support has helped Carter through his treatment, especially one generous gift from a 19-year-old student who delivered Spider-Man pajamas, which will be serving as Carter’s Halloween costume, according to WKMG.

McPherson is still accepting cards, which can be sent to 933 Copenhagen Way, Winter Garden, FL 34787.
